Broad wrist cuff in polished white gold over a titanium core, 52mm wide, set with a flush BCI interface port at the inner wrist. The outer face carries a tessellated pattern of hand-engraved geometric lines — a fusion of Yoruba adire geometry and Scandinavian knotwork, executed in negative relief so the metal catches light in shifting planes. A hairline ring of pale blue bioluminescent resin traces the port surround.

Worn as both a status signal and a functional interface device. The port connects directly to Spire-tier BCI hardware, allowing seamless neural handshake with secured corporate environments without exposing a raw port.
